The sophomore class is planning to sell school mascot puppets to help cover the cost of a class trip. A local supplier will char
kifflom [539]

Answer:

755 or more

Step-by-step explanation:

The profit is the difference between revenue and costs. We want the profit to be $2000 or more, and we have both fixed and variable costs.

Let x represent the number of puppets sold. Then the costs are ...

... 76.25 + 2.25x

The revenue is 5x.

The above-described relationship can then be written as

... 5x -(76.25 +2.25x) ≥ 2000

... 2.75x ≥ 2076.25 . . . . . add 76.25, collect terms

... x ≥ 2076.25/2.75 . . . . divide by the coefficient of x

... x ≥ 755

755 or more puppets must be sold to earn $2000 or more.

What should be the next number in the following series? 100 96 104 88 120 56 _ ?_
8090 [49]

Answer:

  • <em>The next number in the series 100, 96, 104, 88, 120, 56, ... is</em>: <u>184</u>

Explanation:

1) You need to try to find a pattern in the given sequence, so that you can conclude a rule to determine each number in the sequence.

2) The first logical approach to find such pattern is to find the differences between any pair of consecutive numbers. That leads you to this:

  • 96 - 100 = - 4
  • 104 - 96 = 8
  • 88 - 104 = - 16
  • 120 - 88 = 32
  • 56 - 120 = - 64

3) From that, you can see that the difference between two consecutive numbers is scaled by a factor of - 2. That is shown here:

  • First difference = - 4
  • Second difference = 8 = - 4 ( - 2)
  • Third difference = - 16 = 8 (- 2)
  • Fourth difference = 32 = - 16 ( - 2)
  • Fifth difference = - 64 = 32 ( - 2)

4) Therefore, in words, the rule is "add (- 2) times the previous difference", which is:

  • - 64 ( -2) = + 128

         ⇒ 56 + 128 = 184.

         ⇒ Answer: the next number is 184.
